Overview:

67-70 Mustang Tri Y 390-428 Silver Ctd

JBA long tube headers are the number one choice for maximum performance gains and high RPM efficiency. Available in 409 or 304 Series Stainless Steel. These long tube designs are dyno and race proven to deliver the greatest possible increase in horsepower and torque throughout the RPM range. All JBA long tube headers feature large mandrel-bent stainless steel primary tubes, oversized exhaust ports, extra thick 3/8 one-piece flanges, and proprietary JBA Firecone® merged collectors for smooth flow. Each system is designed to give the maximum amount of ground clearance possible, so lowered cars do not drag the collectors.

Features:

  • 3/8" thick CNC laser-cut flanges
  • Patented JBA Firecone® collector
  • O2 sensor provisions
  • Large diameter mandrel-bent steel tubes
  • Oversized exhaust ports

    Way too narrow
    Size: 9.5 Wide, Color: Burgundy Polished Full Grain
    I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

    I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
    Size: 11, Color: Burgundy Polished Full Grain
    5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

    Great price great shoe
    Size: 12, Color: Burgundy Polished Full Grain
    Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.

    Quality shoe but with a slight squeak.
    Size: 10 Wide, Color: Burgundy Polished Full Grain
    Nice shoes with the classic Penny Loafer design. Fit was better than another brand I tried. Only reason not 5 starts is disappointment due to a slight squeak at times when walking.
